PA'IERjSON, NEW JERSEY, A CORPORATION OF NEW COP-WINDING MACHINE.

Application filed December 19, 1825. Serial No. 78,480,

The present invention relates to cop winding machines and is herein shown as embo died in a machine for winding from waxed thread a flat disk-like cop for use in a discoidal sewing machine shuttle.

provide a machine by which aflat disklike cop of waxed thread may be wound easily and conveniently without any particular skill or care on the part of the operator and from which the completed cop may be readilv and quickly removed without any l1ability of injury or distortion.

With this object in view the invention consists in an improved cop winding machlne having its various parts Constructed and arranged to operate as hereinafter described and claimed.

A machine embodying the present lnvention comprises two flanges between which the cop is wound and which serve to support the coils of thread at the ends or side faces of the copand retainthe shape of the mass of thread as it is built up, a winding shaftupon which the cop is wound, and a driving shaft for rotating the winding shaft during the cop winding operation. Features of the invention relate to the manner in which the winding shaft is mounted so as to be longitudinally movable into and out of winding position and intov and out of engagement withthe driving shaft, to the means for read ily moving the winding shaft into and out of 'position and for holding it in winding position to the simplified constructlon for holding the end of the thread at the beginning of the winding operation, to the construction and arrangement of the parts permitting the flanges and winding shaftto be properly heated, and to other details of construction and arrangements of parts hereinafter described. Y

Referring to the accompanying drawings,

Fig. l is a view in side elevation of a cop winding machine embodying the present invention, the parts being shown 1n the position which they assume at the beginning of the winding operation; Fig. 2 is a vertical sectional view of the machine'with the base portion shown in side elevation; Fig. 3 is a view similar to Fig. 2, but with the parts shown at the completion of the windingoperation and with the winding shaft withdrawn to permit the completed cop to be removed; Fig. 4 is a detail horizontal sectional view of the parts in the position illustrated in Fig.

cop which is formed by the machine.

The winding flanges between which the cop is wound are indicated at 6 and 8. Of these flanges the flange 6 is rigidly secured to a driving shaft 10, and the flange, 8 is loosely mounted upon a Winding shaft 12. The shafts 10 and 12 are mountedin bearings formed in standards .14 and '16 projecting upwardlyfrom a base 18, the two shafts being in axial alignment and the winding shaft 12 being movable longitudinally towards and from the driving shaft but always maintaining its position in axial alignment with the driving shaft. The belt pulley 20 u 3; and Fig. 5 is'a view in endelevation of the The object of the present inventlon is to' is loosely mounted upon the driving shaft means of a clutch sleeve 22 splined upon the driving shaft and operated y a bell crank lever 24 connected .to a starting and stopping treadle by a link 26.

The winding shaft 12 is rotated only at such times as it is engaged with thesha'ft 10, and in order to cause the winding shaft toberotated it is provided at its inner end with a projection 28 adapted to be received in a corresponding slot 30 in the end of the driving shaft 10. 1'

The flanges 6 and 8 are provided with opposed parallel faces, and these faces are maintained a fixed distance apart so that they constitute walls between which the coils of thread forming the cop can be received and by which the coils of thread are supported and the entire mass of thread formed and retained in the required shape as it is built up into a cop. To maintain the opposed faces of the flanges at a fixedconstant distance from each other the fiange 6 is'siecuredto the driving shaft 10, and the flange8 is provided with a groove 32 which is engagedby a plate 34 se-- cured'to or formed on 'a rod 36 mounted in tween the adjacent ends of thewinding and driving shafts, and thus when the cop is c0 mpleted, as illustrated in Fig. 5, the inner end of the thread is in a position .to permit it to be readily withdrawn so that in using the cop the thread can be withdrawn from the reenter of tee cop.

After] suiiicient thread has been wound upon the winding shaft to form the cop, the thread is severed from the supply, and the winding shaft is withdrawn completely from the interior of the cop which is'stripped from the i indingshaft" as the shaft is withdrawn by the flange 8.' The withdrawal movement of the winding shaft is inan axial: direction and. when completely withdrawn froinbetween the winding flanges the winding shaft still remains snugly fitted in its hearing; The construction for supporting and rotating the Winding'shaft is thus extremely simple and efficient and permits the operator readily to move the winding shaft into winding position and to remove it fromthe completed cop without any particular care or skill and-without any liability of injuring or distorting the completed cop. This manner of supporting and driving the winding shaft also permits the winding shaft and flangesito be heated readily and in an.efiieient manner, as will be hereinafter described, I so that the copof waxed thread may be readily removed from: the machine without injury.

As a convenientfmeans for moving the winding shaft into and outof windingposition, the outer end of the shaft is (provided with a block 42 rotatably mounted thereon from which projects'pins 44 whichare en gaged by a slotted fork at the upper end of an arm46 provided with an operating: handle 48. To hold the winding shaft securely in winding position a locking device in the form of a leaf spring 50 is secured tov the bearing post 16 and provided with a-hole 52 arranged to'be engaged by a pin 54 on thearm-46 as the winding shaft reaches its extreme inwardpo sitionv To limit the outward movement of, the windingshaft a guard, or stop, 56is pro vided consistingiof a plate, secured at one end to thebearing post 16 and having its other end bent into a position to extend across the outer. end of the winding shaft.

The base 18 of the machine and also a por-. tion' of the bearing posts 14 and 16 are made hollow to form a chamber to which steam is" supplied through suitably arranged pipes, one of which is shown at 58. The bearing. postsare thus heated, and by reasonofthe snug fit of the shafts 10 and 12 in the bearing posts heat is conducted in an efficient and satisfactory manner to the shafts and through the shafts to theiwindingv-iangesfi and 8.
